Efficient Agent-Based Dissemination of Textual Information
- …Abstract. We study the problem of efficient dissemination of textual information over wide-area networks. Our dissemination architecture utilises middle-agents and sophisticated matching algorithms. The data model and query language is based on the well-known Boolean model from Information Retrieval…

P2P-DIET: an extensible P2P service that unifies ad-hoc and continuous querying in super-peer networks
- …The main application scenario considered in recent peer-topeer (P2P) data sharing systems is that of ad-hoc querying: a user poses a query (e.g., “I want music by Moby”) and the system returns a list of pointers to matching files owned by…

Query Processing in Super-Peer Networks with Languages Based on Information Retrieval: the P2P-DIET Approach
- …Abstract. This paper presents P2P-DIET, an implemented resource sharing system that unifies one-time and continuous query processing in super-peer networks. P2P-DIET offers a simple data model for the description of network resources based on attributes with values of type text and a query language …

LibraRing: An Architecture for Distributed Digital Libraries Based on DHTs
- …Abstract. We present a digital library architecture based on distributed hash tables. We discuss the main components of this architecture and the protocols for offering information retrieval and information filtering functionality. We present an experimental evaluation of our proposals. 1…

Architectural Alternatives for Information Filtering in Structured Overlay Networks
- …In this work we discuss how to provide information filtering (pub/sub) functionality over peer-to-peer structured overlay networks by presenting two approaches we developed. Both approaches utilize the Chord DHT as the routing substrate, but one stresses retrieval effectiveness while the other relax…

MinervaDL: An Architecture for Information Retrieval and Filtering
- …Abstract. We present MinervaDL, a digital library architecture that supports approximate information retrieval and filtering functionality under a single unifying framework. The architecture of MinervaDL is based on the peer-to-peer search engine Minerva, and is able to handle huge amounts of data p…

Selective information dissemination in p2p networks
- …We study the problem of selective dissemination of information in P2P networks. We present our work on data models and languages for textual information dissemination and discuss a relevant P2P architecture that motivates our efforts. We also survey our results on the computational complexity of thr…

ABSTRACT Node Behavior Prediction for Large-Scale Approximate Information Filtering
- …In this paper we investigate methods that allow us to identify the publishing behavior of individual nodes in large-scale distributed information filtering systems. The work presented here is based on our system MAPS (Minerva Approximate Publish/Subscribe), a novel approach to support approximate in…
